    pervasive: examine use of "UNUSED"
    
    This would be better named MAY_BE_UNUSED since code is allowed to
    use things declared UNUSED.
    
    - v2_proposals.c parse_proposal: "proposals" is used
    
    - lsw_get_xauthsecret: eliminate unused arg "connection"
    
    - sign_hash_ECDSA: eliminate unused arg "hash_algo"
    
    - whack.c check_end: eliminate arg "default nexhop"
